Erwin is a quantum 3D sliding puzzle game, built exclusively for the iPhone.
Ad-free, tracking-free so you can enjoy your game without interruptions.
Erwin is a sliding puzzle played on the six faces of a 3D cube, each a 4×4 grid.
Swipe to slide and merge tiles, swipe the background to rotate the cube and work the other sides.
Tiles have value, starting at 2 and doubled with each merge: 4, 8, 16 and so on. Each merge adds to your score.
Play long enough and quantum effects begin to appear: some tiles are in superposition, alternating between two values. Swipe them as any tile to collapse to whichever value enables a merge.
Erwin respects your privacy and your wallet. This is an app I wanted for myself, without compromise or dark patterns: it has no ads, no sponsorships, no tracking, no analytics, no profiling, no nagging, no in-app purchases. Pay once, and play forever.
